Distributed Ocean Data Reduces Errors in Marine Weather Forecasts

To improve ocean insights and forecasts, Sofar operates the largest privately owned ocean weather sensor network in the world (see figure 1), currently consisting of nearly 200 real-time weather sensors in the Pacific. Each sensor measures wave conditions, surface winds, and drift currents, and transmits the data to the Sofar cloud in real-time. We assimilate the data in our wave forecast models to create the highest fidelity wave forecasts in the world. Compared to NOAA models, the Sofar data network reduces model rms errors by more than 20% across the board (see figure 3) and more than 50% in high-energy swell forecasts (see figure 2). The best part? All our real-time sensor data and enhanced model forecasts are publicly available at weather.sofarocean.com

On December 27th 2019, an energetic storm system developed in the western Pacific about 1000km east of the Japanese coast (figure 1). The extreme surface winds generated 30m waves, taller than a 7-story building. These energetic waves radiate across the northern Pacific basin, first approaching Hawaii and then making their way to the west coast of the United States.
